Bug tracking for stable and beta releases as well as feature tracking are available on a dedicated site http://opencpn.willkamp.com/ (for now replaces www.opencpn.org/flyspray/).
Please check if the bug or feature is already reported before entering a new report or request.
It is not necessary to register, to use the site, but more features are available if you do.
The sticky thread “Tracker/Flyspray - How and When to use it” is giving some hints.
